Thanks @steakster I will investigate
Modest levels in a modest room 94 sensitivity. The amps are wired straight to the mid range drivers. Not much power is needed on these speakers w class d amps on the dual 15s @audphile1 . 30W a side is plenty.
Allnic Audio A-6000 vs Pass XA 30.8
Maybe an unfair A/B ... yet FYI
After a 17 day x 24 hour burn in of the Pass at solid levels running music I had a listen to trusted digital files I've heard for 20 years as my REFs ... hoping there was a SS amp that could rival the Allnic. The A-6000s are stock internally, running 2 x EML 300 BXLS on each side. Mullard drivers. Gain between the amps was within 0.5 db of identical.

Allnic was superior in every category:
Low end had more size, more extension, and more transient punch
Low level details were more resolved, more depth, more beautiful overall image
Harmonic differences of digital vs analog tape tracking in these well known reference recordings were masked by the Pass
Lateral size of both was similar
Midrange freq hardness around 1-3k with the Pass
Strong signature on every playback option that was very obvious. I heard the amp as much as the music
